7. Cherries

With the exception of the fleshy part around the seed, cherry plants contain cyanide and are toxic to dogs. Cyanide disrupts cellular oxygen transport, which means that your dog’s blood cells can’t get enough oxygen.

8. Apple Seeds

Apple seeds contain amygdlin, a form of cyanide, which is very poisonous to every living thing. Cyanide prevents the blood from carrying oxygen throughout the body.
